AppIic-atian filed October 18, 1926.

'My invention has reference to improve ments in syringes and more particularly to vaginal syringes.

I-leretefore, no satisfactory vaginal syringe has been provided which will thoroughly cleanse the walls of the vagina and it is therefore the object of the present invention to provide a novel and practical construction of syringe by which the walls of the vagina can be thoroughly cleansed and irrigated in combination with novel means to dilate the vagina by water pressure to any desired amount or extent, and to retain such position during the process of cleansing, for purposes hereinafter set forth.

Another object of the invention is to pro vide a syringe with a novel form of hollow injector tube, said tube having a plurality of discharge slots at its forward end positioned between several radially extending flanges and the whole positioned in such a manner so that when the syringe in position, the cleansing fluid is discharged at the innermost portion of the vagina, or mouth of the Womb in a harmless film like spray, after which one of said slots will serve as an unobstructed air passageway between the forward end of the hollow injected. tube and the outwardly formed drain channel for purposes hereinafter explained.

Another obj cct of the invention is to provide a syringe of novel construction which will when in position, harmonize perfectly with natures forces, whereby a woman may be relaxed flat upon her back during the process of cleansing and. the entire remaining fluid will be drained from the vagina. Heretofore, it has been ditlicult to drain the vagina and no practical means has been provided for thoroughly doing this, with the result that the cleansing fluid has to a certain amount, been left in thevagina after the syringing operation. In accordance with the present invention, the earths force of gravitation as it is exerted upon the air, water and human body is fully reckoned with.

Another objectof the invention is to provide a novel valve control for the drain or discharge of the cleansing fluid after carrying on its work in the cleansin operation.

Other and further objects will appear as the description, proceeds.

Referring to the drawings in detail, in which like reference characters designate corresponding parts throughout the several v ews, and referring to Figures 1 to 6 inclusiye as well as the form of nozzle shown in Figure 7, the device comprises an elongated ln ection tube 1 which is provided at its forward end with a plurality of radially extending tapered flanges 2 which give a star shaped appearance at the forward end of the tube. These flanges start from the point 3 on the body of the tube externally at the sides and top and nearer the forward end than the rear end and are preferably four in number. although any other number niav be provided, and gradually increase in depth or radial dimension and extension from the periphery of the tube through the sloping walls 4; and then extend parallel to the external surface of the tube and axis thereof to the forward end, at which points they are provided with curved edges 5 of convex formation curving inwardly toward the tip of the nozzle and tapering as shown at 6 so as I to form a relatively central concavity or recess at the point 7. Between these flz rnges are positioned a plurality of radial slots 8 of elongated formation extending bacl; slightly into the body of the tube andhavinp; forwardly diverging inclined or slanting walls 9 at the rear ends thereof so as to discharge the water or cleansing fluid outwardly and forwardly in radial spray like sheets which prevent injury to the parts treated within the vagina and at the mouth til of the womb. The radially extending flanges are so positioned in relation to the injector tube that when the syringe is in position, the outward surfaces of the two bottom flanges rest upon the same horizontal plane. tube externally of its wall are a pair of depending or downwardly extending parallel flanges which are relatively wide and tapered at their forward ends as indicated at 11 in a corresponding manner as the'flanges 2, between which one of the slots 8 is medially positioned to discharge between the forward ends of the flanges 10. These flan es extend downwardly and rearwardly from the tip of the nozzle at the bottom, the entire length ofthe injector tube, "thus forming with the wall of the tube 1, thetop and side walls of a channel 11 which is relatively narrow and deep in construction, being considerably deeper than wide and the inner top wall ofthe channel maybe coucaved or the inner portions of theinner faces or surfaces of the flanges 10 may converge inward-- ly or diverge outwardly so as to slope sligh ly toward each other toform a concave rounding inner or top wall for the channel while the bottom is freely open the channel as before stated being deeper than wide as specifically designated by the dotted circle in Figure 3 of the drawings. The flanges 10 are also provided with a plurality of spaced parallel and transverse or vertically'extending slots 12 which as shown extend part way across the flanges 10 and substantially, throughout the length thereof as seen in Figure 1, except at the forward ends which have their edges curved and the im ges tapered gradually upward toward their forward ends and finally terminate at the tip of the injector nozzle nearthe point- 7. Atthe rear portion of the nozzle, thelatter is formed with a substantially annulari shaped flange or collar 13 which extends around the rear end of the tube-from the top to the bottom along the sides but terminates on either side by emerging into each rear end of the extended flanges 10 at the 30tt0l1'1, thereby allowing the before men tioned channel 11 to continue to the rear unobstructed. This is due to the fact that the collar 13 is of substantially horseshoe shape or U'-shape with the sides tapered downwardly and rearwardly toward the bottom and curved rearwardly and downwardly to a point across the width or depth of the collar as specifically seen in-Figure 1 to properly fit the mouth of the vagina.

The injector tube is also extended rear wardly beyond the collar 18' as indica ed at 1% and externally threaded at its rear end as indicated at 15 forming the inner end of the injector tube so asto support a stopper or shield 16 on the portion 14 in slightly spacedrelation to the collar 18 as indicated Formed along the bottom of f'tllQ'c.

at 17 to form a narrow passage way r up with respect to the adjacent side or face of the collar 13 for the purpose to be hereinafter more fully described. The stopper or shield 16 tapers forwardly and at its rear end, .isicut" out or concaved to form an interior hollow portion 18 to accommodate an internally threaded nipple 19 which enga the threads l5'and abuts up against a shoulder 20 formed at the inner wall of the concavity or hollowed out port-ion whereby to retain the stopper or shield in position detachably, thereby permitting parts to be readily separated for sterilizing or cleansing, and maintaining the same in an extremely sanitary condition. over the inner end of the nipple 19, which beaded as at 20 for this purpose and may c-Xtenu from a suital'ile reservoir in the form of a hot water bag, bulb or other means of supplying the cleansing fluid to the nozzle.

The stopper or shield 16 is provided with an outlet or drain passage 22 which in line with the channel 11. at its 'lorward end, separated only by the narrow passageway 17 and slanting downwardly in an inclined position through the shield body while the rear portion thereof eXtends horizontally and is notched, serrated or threaded internally, as indirated at 23 to take a nipple 2i beaded shown at- 25 for engagement by a flexible drain tube 26 adapted to lead to a suitable drain receptacle or waste pipe such as a closet bowl. The nipple 2 1 is serrated or threaded to engage the portion 23 to secure it in position and has its forward end tapered and provided with slots 27 extending radially while theforwa-rd end is concared to form a peat 28 for a ball or other check valve 29. i

This check valve 29 is adapted to close against the seat 30 thereby preventing bacl; low of the cleansing fluid after it has served its purpose and has drainedpast the valve, but permitting the discharge or drain thereof through the openings 27 when the ball check valve is'unseated as to teat 30 but is against seat or concavity 28 as shown in Figure 1 of the drawings to permit the discharge through the tube or pipe 26 as indicated by the arrow. The induction into the pipe or tube 21 is also indicatcd by the arrow at the upper extremity thereof supplying the cleansing fluid under a pressure head either natural or forced from a suitable receptaclc or bulb.

A regulating or hose clamp is adapted to be positioned over thetubcs 21 and 26 in such a manner that both tubes may a compressed simultaneously to stop the flow of liquid through the same, or the drain tube 26 may be closed any desired amount prior to the closing of the inlet or supply tube 21, all of which is accomplished by the manipulation of a single control. lever 81 for the A supply tube 21 fits purposes and in the manner to be subse quently described. This regulating or hose clamp constituting a shut-off tor the flow of fluid consists of a flat body 32 which is arranged beneath the tube 21 in use, pretcn' ably consisting 01'. a section of spring 01' resilient metal with two corrugations tormed by a hump or raised part 33 and a depression 3 ltor the purpose of making better contact with the tube in the shutting oli process. On either side of the corrugations is a set of guides and 36, both oi annular formation and the former extending upwardly and adapted to receive the tube 21, while the latter extends downwardly and is adapted to receive the drain tube 26 for holding the tubing in place. One end of the body or plate 32 is bent up and turned back in spaced relation to the body as indicated at 37, this end being provided with an opening tolikewise receive the tube 21 and this opening centering with the corrugations 34: and 35 and the tube guide 35, the whole of which gives a resilient or spring-like effect to the device.

Near the end of the spring at the top on either side, is provided an offset lu; which protrudes through the top holes 39 of lever 31 having enlarged parallel side portions 40 for this purpose and form a pivot axis allowing the lever 31 to swing on a radius of about 180 degrees from that point,

dragging with it a U-shaped bail or band ll which is hung'from side portions 420 and disposed to surround the discharge tube 26. The ends of the hand all are directed or bent inwardly through halt round holes 1-2 in the side portions or jaws l0 of the lever 31, these openings or holes having circular bot tom portions and straight top walls all oilset from the center lug 38 and apertures The free end of" the top portion or sprung 413 is provided with a. de n'ession or lug l l opposite or above hump and the lower portion of the plate proper is extended bc yond the band or guide 35 as indicated at 15 to provide a finger grip or handle 18 adjacent the rear end oi? the clamp, with. which the user may hold the clamp and syringe securely in positioi'i with one hand, thereby allowing her a tree hand with which to operate the control lever 31.

The operation of the vaginal syringe will now be described.

The person desiring to use the syringe lies flat upon her back (thereby relaxing all the tension on the muscles) and the injector tube or nozzle 1 inserted into the mouth of the vagina until the stopper or shield 16 completely seals the same, as indicated by dotted lines A in Figure 1. The torward end of the injector tube will then be close to the bottom of the vagina. the wa l oi which is designated in an inflated posi at B in Figure 1, while the mouth of the womb is designated at C. The hose clamp when in position presses against the rear end of the injector tube by raising the lever 31 and moving it to the dotted line position shown in Figure 1 to close the tube 21 betwren the corrugations 33, 34 and 44-, at which time the ends of the U-shapcd bail or hand ll is also drawn against the drain tube 26 to simultaneously close it while the end 44 is pressed down in opposed relation to the part 34, and in this position the straight walls 42 are engaged by the inwardly extending upper ends of the bail or band l1 to retain the device in this position by the spring tension. lVith the aid of the linger grip or handle 46, the wholeis held in position with but one hand. The clamp is opened after the proper supply of cleansing fluid has been provided from a douche receptacle or syringe bulb above, in this case preferably a hot water bottle or other container for the cleansing fluid which is elevated to secure the proper pressure head and the clamp being opened, the tubes 21 and 26 are opened, which allows the cleansing fluid to freely pass through the iniector tube 21 and slots 8 thereof to spray the interior of the vagina and walls thereof and at the mouth of the womb in star shaped spray-like sheets shown as X being six in number in the drawing and especially il lustrated in Figure 6 assuming a bladed, fan-like or butterfly ettect. Due to the tapered thickness near the tip of the side walls of the slots 8, an uneven. resistance to the flow of fluid occurs which causes same to alter its course and merge into a star.

shaped harmless film-like spray which makes contact with the vagina at the innermost point where cleansing begins. ts the fluid continues to be discharged througl'i said slots, it takes an upward course but remains in continuous contact with the walls of the vagina. thereby cleansing entirely where it finally enters the outlet or drain passage termed by the channel or groove 11 due to the latter fitting against the walls of the vagina and partly due to the drain through the slots 12. Owing to the channel 11 being relatively deep and narrow. being deeper than wide, the bottom edges of the flanges 10 are contacted with the walls of the vagina when the latter are not being dilated due to back pressure as shown in Figure 1 of the drawing and as will be subsequently described, thus forming a continuation of the drain channel through the groove beneath the nozzle formed by the flanges 10 across the space 17 at the bottom of the horseshoe shaped collar 13 and out through the drain passage 22 when the valve 29 is unseated, permitting the fluid to escape through the tube outlet 26. The narrow passage *av or space 17 is also sealed by the walls of the vagina as clearly indicated at Figure 1 ct til) -which will close the drain tube 26 to any desired amount or degree and permit a faster flow of fluid into the interior of the vagina than the out-flow therefrom, owing to the supply tube being open slightly at least, until such time that the accumulated fluid pressure dilates the walls of the vagina as disclosed in Figure 1 of the drawings thereby straightening out all the folds and thoroughly cleansing and sterilizing the same, By holding fast the clamp of the control lever in an upward midway position or other intermediate position as desired according to the degree of dilation which may be required, found necessary or comfortable, the said condition may be continued until a thorough cleansing is assured. It is of course, to be understood that in this dilated condition, all parts of the walls of the vagina and the mouth of the womb may be dilated, thoroughly washed and cleansed and that as soon as the lever 81 is moved back to its original position, this fluid may be discharged through the tube 26 and drained off into asuitable receptacle or 'aste outlet. I

When the supply of cleansing fluid is ex hausted, a quantitiy of said fluid becomes trapped within the interior of the vagina and injector tube due to the fact that the drain passage 22 and the upper portion of the drain tube 26 are on a higher level than the interior of the vagina and the injector tube inserted therein owing to the reclining position of the patient or user. The vagina and injector tube are now emptied of the contents in the following manner: The fluid which fills the drain tube 26 continues its downward course due to its own weight thereby creating a partial vacuum or suction within the walls of the vagina, whereupon the constant air pressure against the outside of the vagina walls, viathe body causes it to collapse or flatten beginning at the top and extending downwardly thereby forcing the fluid downward. This es may be caused partly through the slots 12 in addition to the opeuine; at the front of the channel 11 formed by the flanges 10. it first, the fluid is pushed out throug he passageway orspace 17 whlch 1s hi host,

and which is open at the top and leads into the space between the channel 11 and the drain passage 22 forcing; the fluid into the drain passage 22 and then into the drain tube 26 until the vagina is flattened around the stopper 16 as shown in Fi 'ire l, and

downward, whereupon said vagina flattens across and around the passageway 17 as shown in Figure 1, which is specifically narrow and deep in construction so as to prevent the air pressure from forcing a portion of the soft tissue of, the vagina deep into the same whereby it would be rendered useless as a passagewa: between the drain passage 22 and the channel 11, for purposes hereinat'ter explained. There is also a constant pressure of air upon said tluid contained in the injector tube via the supply tube 21 from the pressure caused in the receptacle or bulb containing the cleansing fluid. As the draining action continues, the vagina walls collapse around the flange or collar 18 and the injector tube 1 and across the bottom edges of the two extended flanges forming the channel 11 thereby closing the bottom of said channel 11 beginning first at the top and then downward as the action continues. As the fluid is forced downward it readily enters the channel 11 at or below the water level at the front end. or through openings or slots 12, where it is forcedupward through the channel 11 and passageway 17 into the drain passage 22 and finally entering the drain tube 26 past the val e 29 where it discharges into a receptacle that is on the floor. This action continues until the last remaining fluid is forced into the channel 11 and the vag na has entirely collapsed around. the drain tube and across the edges of the two extended flanges 10, thereby sealing the channel 11 and the remaining contents therein except for the outlet passage into the passageway 17 at the bottom. The final draining of the channel 11, passageway 17 and drain passage 22 is accommodated as follows: The atmospheric pressure now enters through the supply tube 21 and hollow injector tube 1 where it passes into the bottom or the forward end of the channel 11 through the lower discharge slot 8, thereby forcing:- the ren'iainingr fluid upward through the channel 11 and passa ieway 17 into the drain passage 22 where it passes into the drain tube 26 and drains as before stated. When the action finally ceases and the vacuum is broken. the check valve 29 rolls against its seat 30, thereby preventing a possible baclztlow of a few drops that may adhere to the drain ube 2%).

In practice, I find it essential that the channel ll must be specifically narrow and deep in construction and especially deeper than wide and substantially so, so as to prevent the air pressure from pressing the soft tissue of the vagina deep into the same whereby it would be rendered useless as a drain passage, the channel in this manner being closed on all sides while the tissues also close the slots 10 or substantially so. It must also extend the entire length of the injector tube w th a passageway at the forward end directly between and the hollow injector tube due to the tapered formation of the flanges 10 at the front as indi cated at 11. WVith this means, a thorough cleansing and draining is provided which heretofore has been impossible.

In addition to the preferred form of syringe above described, I have also provided a modified form, equally efficient, but of a more compact type, shown in Figures 7 and S of the drawing, in which the threaded enlargement 49 of a nipple 50 having a head or head 51 over which a tube "2 is fitted, said tube 52 connecting to the bottom of the valve and bearing the regulating and controlling device 32 the same as previously described with exception that the parts 33, 36, 15 and 16 are omitted and the part is left partially open as indicated at 53 and a projection 54L is provided on the plate portions 40. A bulb is also provided on the free end of the tube 52. a

The upper end of the casing 48 is internally threaded to receive an aperture plug 56 which is externally threaded for this purpose and provided with air vents or grooves 57 at one or more sides thereof around the stem 58 of a piston 59 which is slidably mounted in the casing 18. This piston is of hollow sleeve-like formation and has its upper end apertured for connection with the stem 58 as by means of the screw or the like/60. The stem also has a pressure button'61 at its upper end for exerting pressure thereon to shift the piston against the action of the spring 62 which is positioned between the apertured upper wall of the piston or screw and a suitable seat 63 in the bottom of the casing at the part 50 around the drain opening 64t thereof. The piston has a slot 65 leading through one side and itslower end is tapered outwardly as shown to direct the fluid through the hollow channel 66 of the piston and through the port or slot 65, which latter is considerably longer than the diameter of either of the passages leading from the valve casing.

These passages are indicated at 67 and 70,

passage 67 in the upper inlet extension or nipple 68 being internally threaded for engagement with the external threads 15 as indicated at 69 and leading into the injector nozzle or tube 1. The nipple 68 also forms a shoulder to retain the stopper or collar 16 in position. The lower channel or passageway 70 leads into the drain outlet 22 and has a flange 71 which closes against the outer end of the passageway at its horizontal portion 23 serrated to secure it in position in the manner as heretofore described in connection with the structure shown in Figure 1 of the drawing and containing the ball valve 29 also as previously described. The piston 59 may be made of hard or soft rubber or other material and is held up in place by the coil spring 62 as described, which spring may encircle the valve stem or may be placed .inside of the piston and terminating at the nipple 50 as indicated or in any other suitable position. The tube 52 is preferably a short length of rubber tube about 12 inches long over which is placed the single purpose hose clamp described as a modification of the clamp 32 previously referred to. A single ended valved or valveless rubber bulb 55 is secured to the opposite end of the tube and the device is now ready to use.

In the use of this device, the bulb is compressed as much aspossible, the slots 8 in the forward end of the tube or injector nozzle submerged into the fluid contained in a suitable receptacle and the bulb released which allows the fluid to be drawn through the injector nozzle or tube 1 and through the slot 65 into the tube 52 and into the bulb which allows the bulb to fill, owing to the bulb being released. The injector tube is now raised and the bulb squeezed until the fluid appears in the slots 8, and when in this position the hose clamp is closed by swinging the lever 31 over in the manner previously described from the intermediate position shown in Figure 7. hen in this position, the hose clamp is closed and the syringe may be now placed in position in the vagina in the same manner as shown in Figure 1 of the drawing. The hose clamp is then opened and by squeezing the bulb, it will produce a star spray douche effect. after which the user releases the bulb and with the free hand pressesdownward on the press button (31 which carries with it the piston 59, moving the slot (35 downward over the passageway 70 and away from the supply passage 67, allowing the air pressure to pass through the air space between the top of the piston 59 around the valve stem and the vents 57 and enter the injector tube. This causes a siphoning action which drains the vagina in the same manner as before stated, the drain being through the passageway 22, passage 70 through slot 65 into the bottom of the casing 48 of the valve 47 and through the nipple 50 into the tube 52 and bulb 55 from which it may be discharged and the parts cleansed in any suitable way.
